Rudy Project glasses

Has anyone used or know someone who has used the Rudy Project Rydon shooting glasses? What were your thoughts? likes, dislikes? Per their website, the glasses look nice, I am just curious whether the top of the glasses (frame)would obstruct your view while shooting.

I have been using the Rudy Project Rydon prescription Shooting glasses for a year now and I love them. Because of my prescription None of the other manufactures could provide me with suitable shooting lenses. They would be too thick of a lense, but with the rudy set-up (inserts inside the frame) I now have a lightweight set of shooting glasses with five different color sets of lenses. There is no obstruction of sight plane with the frame.

If you go to there web site you will see that they have a special 5 color lense
special for the rydon. Also the Rudy Project warranty is really great.
